The medieval aqueduct of Salerno was built in the ninth century to supply water to the monastery of St. Benedict, at the eastern walls. It is located in the historic center of Salerno, under the hill Bonadies and its Arechi Castle.
It consists of two branches: one coming from the hills to the north, the other one from the high ground to the east of the city; both rejoined along the street Arce (which by their arches is named), at an edge of the old city walls. At first only stocked the Benedictine monastery, and later, a branch underground allowed to supply the convent of Piantanova, Via Mercanti.
The aqueduct was popularly renamed 'Bridges of the Devil' and it was said that it was built in a single night, with the help of demons, by the magician of the twelfth century Peter Barliario. The popular superstition considered also that venture under the arches between dusk and dawn would bring to the meeting with devils or evil spirits.
References:Celje Castle was once the largest fortification on Slovenian territory. The first fortified building on the site (a Romanesque palace) was built in the first half of the 13th century by the Counts of Heunburg from Carinthia on the stony outcrop on the western side of the ridge where the castle stands. It had five sides, or four plus the southern side, which was a natural defence. The first written records of the castle date back to between 1125 and 1137; it was probably built by Count Gunter. In the western section of the castle, there was a building with several floors. Remains of the walls of this palatium have survived. In the eastern section, there was an enclosed courtyard with large water reservoirs. The eastern wall, which protects the castle from its most exposed side, was around three metres thicker than the rest of the curtain wall. The wall was topped with a parapet and protected walkway.
